Introduction

      SonarQube is an open source web based tool to manage code quality and code analysis. It is most widely used in continuous code inspection which performs reviews of code to detect bugs, code smells and vulnerability issues of programming languages such as PHP, C#, JavaScript, C/C++ and Java, also tracks statistics and creates charts that enable developers to quickly identify problems in their code.

Install and Setup PostgreSQL 10 Database for SonarQube

• Create the file “/etc/apt/sources.list.d/pgdg.list” and add the corresponding line for the repository in it:

     $ sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'

• Import the repository signing key and update the package lists:

$ wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add –

• added the PostgreSQL official repository to our system

                      $ sudo apt-get update

• To install PostgreSQL on Ubuntu, use the apt-get (or other apt-driving) command:

                     $ sudo apt-get -y install postgresql

•   Update Postgres account Password

                    $ sudo passwd postgres

                    $ su – postgres

                

• Create a user and database for Sonarqube

            postgres@manikandan-VirtualBox: $ createuser sonar

             postgres@manikandan-VirtualBox:~$ psql

 

            postgres=# ALTER USER sonar WITH ENCRYPTED password 'sonar123';

 

            postgres=# CREATE DATABASE sonarqube OWNER sonar;

           postgres=# grant all privileges on DATABASE sonarqube to sonar;

           postgres=# exit

           postgres@manikandan-VirtualBox:~$ exit

Install and configure SonarQube

• $ sudo wget https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-8.9.1.44547.zip
  
  
  

• $ sudo unzip sonarqube-8.9.1.44547.zip
  
  
  

• $ sudo mv sonarqube-8.9.1.44547 /opt

• $ cd /opt

• $ cd sonarqube-8.9.1.44547/
  
  
  

• $ sudo gedit sonar.properties

           Remove the # symbol on the below line in sonar.properties

             sonar.jdbc.username=sonar

             sonar.jdbc.password=sonar123

             sonar.jdbc.url=jdbc:postgresql://localhost/sonarqube

             sonar.web.javaOpts=-Xmx512m -Xms128m -XX:+HeapDumpOnOutOfMemoryError

             sonar.web.host=0.0.0.0

             sonar.web.port=9000

             sonar.web.javaAdditionalOpts=-server

             sonar.path.logs=logs

             sonar.log.level=INFO
